## Class UploadBlobServlet

- java.lang.Object
- - HttpServlet
  - - com.google.appengine.api.blobstore.dev.UploadBlobServlet

-     public final class UploadBlobServlet
      extends HttpServlet

  `UploadBlobServlet` handles blob uploads in the development server. The stub implementation of `BlobstoreService.createUploadUrl(java.lang.String)` returns URLs that are mapped to this servlet.

  Its primary responsibility is parsing multipart/form-data or multipart/mixed requests made by web browsers. To minimize dependencies in the SDK, it does using the MimeMultipart class included with JavaMail.

  After the files are extracted from the multipart request body, they are assigned `BlobKey` values and are committed to local storage. The multipart body parts are then replaced with message/external-body parts that specify the `BlobKey` as additional parameters in the Content-type header.
